(Action)

According to such a device, a wireless call can be made using a speed dial.

(Example)

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 3.

2 is a block diagram showing the internal circuit configuration of the telephone according to the preferred embodiment of the present invention.

Referring to FIG. 2, the telephone 100 includes a jack 110 connecting an external telephone line (not shown) and the telephone 100, a dual tone multi frequency (DTMF) tone generator 120, and a control circuit 130. ), A memory 140 and a key matrix 150 having a plurality of speed dial buttons. The control circuit 130 includes a response recognizer 132 and a special number recognizer 134.

The memory 140 stores a phone number corresponding to the speed dial button. The telephone number stored in the memory 140 is the same as a conventional telephone number, but in the case of a telephone number for a wireless call, a special number such as '*' or '#' is added after the call number to be contacted. The number is added. For example, when the call number is' 012-345-6789 'and the telephone number to be contacted is '02 -987-6543', '0123456789 # 029876543' is stored in the memory 140. This is what is stored by the user. In the case of phone-banking, a special number is added after the access number with the host, and then the numbers to be serviced are sequentially entered.

2, the operation of the telephone set of the present invention will be described. When the speed dial button of the key matrix 150 is input by the user, the control circuit 130 reads out a corresponding telephone number from the memory 140 one by one. The DTMF tone generating unit 120 converts the telephone number input from the control circuit 130 into DTMF tones and outputs the DTMF tones to the telephone line.

The special number recognition unit 134 of the control circuit 130 recognizes whether the telephone number read out from the memory 140 is a special number, for example, '*' or '#'. When the telephone number read out from the memory 140 is not a special number, the telephone number is immediately outputted to the DTMF generator 120 to be dialed. If the read telephone number is a special number, the reading operation is held until there is a response from the counterpart.

The response recognizer 132 of the control circuit 130 recognizes whether there is a response from the other party through the telephone line while the read operation is held. If there is a response from the other party, the control circuit 130 controls to start the read operation.

The above operation is repeated until all the phone numbers corresponding to the speed dial button are read out from the memory 140.

3 is a flowchart showing a procedure of a program executed when a shortcut button is input in a telephone according to a preferred embodiment of the present invention.

In step S210, the speed dial button of the key matrix 150 is input by the user.

In step S220, the telephone number corresponding to the speed dial button is read out one by one from the memory 140.

In S230, the special number recognition unit 134 determines whether the read phone number is a special number '*' or '#'. If the read out phone number is a special number, the process proceeds to step S260, where the response recognition unit 132 determines whether there is a response from the other party. In step S260, the device maintains the wait state until there is a response from the other party, and returns to step S220 when there is a response from the other party. If the read telephone number is not a special number, the process proceeds to step S240.

In step S240, the DTMF tone generating unit 120 generates a DTMF tone corresponding to the read telephone number. In the next step S250, it is determined whether the read phone number is the last number of the phone number stored in the memory 140, and if it is not the last time, the process returns to step S220, and if it is the last number, it ends.

In the above, the configuration and operation of the circuit according to the present invention are shown in accordance with the above description and drawings, but this is merely described, for example, and various changes and modifications are possible without departing from the spirit of the present invention. .

According to the present invention as described above, in a telephone having a speed dial button, a wireless call can be made using the speed dial.
